The Avett Brothers line up summer and fall dates

The Avett Brothers are preparing to hit the international tour trail later this week, spending the rest of the summer and the start of the fall canvassing behind a brand-new album.

The North Carolina next hit the stage Wednesday (6/26) with an appearance at Summerfest in Milwaukee, WI. The upcoming round of North American gigs encompasses 13 markets through mid-August, after which the band heads to Europe for a six-date festival run.

A second, more extensive North American outing gets underway Sept. 7 in Ottawa, Ontario, and extending through an Oct. 22 performance in Missoula, MT.

Public on-sales for most dates on the second round of shows go on sale Friday (6/28).

The Avett Brothers are planning to release a follow-up to last year's "The Carpenter" this fall, according to published reports.

"'The Carpenter' was the first installment and this is the other part," Scott Avett said in a mid-June interview with Radio.com. "We initially thought of this as part two…but we realize it's its own thing. It's a very interesting occurrence we didn't intend. It's a nice surprise."

Avett mentioned the effort would likely be released in September or October, but no official drop date has been revealed.
